Recently during a usability tests almost all of our customers complained about the small font size on our website.
We use:
- 26px for headlines
- 13px, bold, for navigation, product names, etc.
- 11px for body text, product attributes, etc.
What would be a good size increase for a site that's filled up with information? The recommended 16 pixels body copy seems to be okay for content sites, but I'm not convinced about it's size for search results and product description in those results - it seems to be way too big. Are there any studies on what's an optimal font for e-commerce search results, product pages, etc?
